Claims. 1

This invention relates to foldable display devices for advertising purposes.

One of the objects of the present invention is to provide a foldable display device of the type which comprises a triangular base and a vertical or upstanding panel with improved means `for attaching the panel to the base.

Another object of the invention is to facilitate the securement of the panel to the base so that the parts of the display device may be easily and quickly assembled in the manufacture of the devices.

The above and other objects, features and advantages of the present invention will be fully understood Vfrom the following description, reference being had to the accompanying illustrative drawings.

In the drawings:

Fig. 1 is a perspective view of a foldable display device embodying the present invention, showing the device set up for use;

Fig. 2 is a perspective view of the lower part of the device, with parts cut away for the purpose of illustration;

Fig. 3 is a sectional view on the line 3-3 of Figi;

Fig. 4 is a vertical sectional view of the device in the folded condition thereof;

Fig. 5 is a plan view ofthe blank from which the base is formed;

Fig. 6 is a sectional view on the line 6--6 of Fig. 2.

Referring now to the drawings in detail, the foldable display device of the present invention comprises a triangular base I0 formed in one piece of cardboard or any other suitable sheet material, and a vertical panel I2 which carries the advertising display on either one or both sides thereof. Panel I2 is also formed of cardboard or other suitable sheet material and is preferably made of cardboard which is thicker'than the cardboard of which the base l0 is formed. It will be noted that there is a slot I4 in the base at the apex `thereof and that panel I2 upstands from the base and projects through said slot, the lower end of said panel being positioned within the base between the opposite sides I6 and I8 andv secured to integral parts of the base as hereinafter more particularly described.

The panel I 0 is formed from the one piece blank IGA shown in Fig. 5. The fold line of said blank is at the apex of the base when the latter is formed from said blank. The lower ends of the sides I6 and I 8 are defined by the fold lines 22 and 24, respectively, at equal distances from the fold line 20. The bottom of the base comprises the parts 26 and 28 of equal width. The lbottom part 26 is provided with an extension or end portion 30 vfoldably connected thereto at the fold line 32. The bottom part 28 is provided with the end portions or tabs 34 and 36 foldably connected to said bottom portion at the fold line 38. vided with a part 40 which is foldably connected thereto at said fold line 38. .It will be noted that part 4I) is positioned between tabs 34 and 36 but is not connected thereto so that said tabs and part 4I! are foldable to different positions with respect to each other at the fold line 38. The relatively foldable parts of the blank IIIA are of such relative widths that the extension 30 of part 26 and the tabs 34, 36 and part 40 project through the slot I4 of the base when the latter is in its flat folded condition as shown in Fig. 4. On the other hand, when the base is in its triangular form parts 30, 34, 36 and 4I) terminate below the apex of the base as shown in Fig. 3 and are in substantial vertical alignment with slot I4. H

As hereinbefore yindicated an important feature of the present invention resides in the manner in which the panel I2 is secured to the base. This feature will now be particularly described. As clearly shown in Figs. 2 to 4 and 6 the lower marginal end of panel I2 is secured to tabs 34 and 36 and to an intermediate part 42 of extension 30 preferably by means of adhesive which is interposed between only one side of said lower end portion of panel I2 andthe adjacent surfaces of tabs 34 and 36 as indicated at 44 in Fig. 6 and between said one side of the panel and the adjacent surface of part 42 as indicated at 46 in Fig. 6. In this connection, it will be observed that the surface part 42 to which the panel is secured is exposed in the space between tabs 34 and 36 so .that the `panel may be disposed at the same side of the inwardly folded end portions of bothk bottom parts 26 and 28. In other words, said inwardly folded end por-A tions of parts 26 and 28 to which the panel is secured are located at the same side of the panel and are relatively positioned longitudinally of the bottom of the base so that the panel may be secured to said end portions of `bothparts of the bottom of the base without requiring that the panel be positioned between said end portions. The stippled area on part 3D and the dotted outline on'the tabs 34 and 36 represent-the areas of adhesive securement of the lower marginal end of the panel to said parts 34 and 36, respec- Said bottom part is also pro- 3 tively. Said dotted outline on tabs 3d and 36 indicate that the surfaces of securement of said tabs to the panel on the one hand, and the surface of securement of portion 3E! to the panel, on the other hand, are on opposite sides of the blank liiA. Accordingly, when .the blank is folded to forrn'the base, said surfaces of portions 39, 34 and 36 all face in the same direction, i. e., toward one side of the base, here shown as side i3 to which bottom part 28 is joined. It will be noted that tabs 34 and 36 are in `abutting face to face relation with adjacent end portions of part Si) but are not directly secured to the latter. On the other hand the adhesivesecurement of panel l2 to tabs 34 and 36 and to the intermediate portion 42 of part 3i] results in the securement of said tabs to part 3U, so that Abottom parts 26 and 2S are foldably connected to each other at their adjacent edges. It will be noted that it is necessary to apply adhesive to only one side of the panel I2 at the lower marginal end thereof for securing said panel tothe base and for securing the inwardly folded end portions 3l), 34 and 36 together.

The inwardly foldable` part 40 is not secured to the panel I2 but is useful as a stop or positioning member forthe lower edge of thel panel l2 during the assembly of said panel with the base and the securement of the panel to parts 3o, 34 and 36. In assembling the panel with the base, after the blank IDA is folded at its several fold lines into theat form illustrated in Fig, 4, the panel l2 is inserted through slot I4 in position between part 40 atone side of said panel and tabs 34 and 36 at the other side of saidl panel, said tabs being in abutting face 'to face relation with part 3c. This positioning of the panel |12 is facilitated by the above described extension of parts 3i), 34, fifi and 40 through slot i4 outwardly beyond the folded edge 20. The inner edge of part 40 at the fold line 38 limits the inward movement of panel l2 through slot i4, in the processof inserting said panel into the base and thus serves as positioning means for thepanel in relation to the base so that the panel may be adhesively secured as hereinbefore described to part 30 and tabs 34 and 36. It will be understood that it is within thek scope of the present invention to omit part vlo and if desired to use some other positioning means, for example, aguide mark on the face of the panel near the lower end thereof; also, it will be understood that part 40 may be of any suitable length.

It will be understood that various changes in the details of construction and in the form of the device and the parts thereof may be made without departing from the underlying idea or principles of this invention within the scope ofthe appended claims.

Having thus described my invention, what I claim and desire to secure by Letters Patent is:
